Thermoformed tray, without lid with product densification.

The thermoformed tray no longer needs a lid, which is the first means of weight reduction. The density is higher:  110 items as compared to 80. This brings a second weight reduction per item, or a total saving of 54%. The tray can be reused at least five times.
